There is a map in the Dorman book
Gunnison showing
one siding stretching back East some 1754ft, the Mp is listed 291 midway along this siding. This map is noted Denver South Park and Pacific Railroad grounds and has the Tomichi Valley Smelter shown between 12th and Boulevard, so as to date this.
ETT's show list nothing until the Aberdeen Br at 292.49, list the C&S Crossing as 288.64 However [
www.drgw.net] lists additional spur at 291.3 as Corlett.
I would be of the opinion that this Otto Perry picture, from
Narrow Gauge in the Rockies, shows the siding off to the right; since I have no more info, nor have I seen any either prior to your chart I can't offer anymore.
